goa

What is goa?

goa is a framework for building microservices in Go using a unique design-first approach. goa provides a novel approach for developing microservices that saves time when working on independent services and helps with keeping the overall system consistent.

goa is a tool in the Microservices Tools category of a tech stack.

goa is an open source tool with 3.8K GitHub stars and 434 GitHub forks. Here’s a link to goa's open source repository on GitHub

goa's Features

Creating a service with goa starts with the design. The goa DSL lets you describe the global properties, types and endpoints that make up the service API. The apidsl package docs provides a quick reference to all the DSL functions.

Once the design of the API is in place goagen generates the corresponding data structures, validation code and handlers. Handlers are defined as interface methods. Implementing the service is thus as simple as implementing the generated interfaces.

The best part about the goa DSL is that the engine is completely decoupled. Plugins can implement custom DSLs to extend the concepts described in the design. Plugins can also generate arbitrary outputs.

Istio

Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio's control plane provides an abstraction layer over the underlying cluster management platform, such as Kubernetes, Mesos, etc.

Kong

Kong is a scalable, open source API Layer (also known as an API Gateway, or API Middleware). Kong controls layer 4 and 7 traffic and is extended through Plugins, which provide extra functionality and services beyond the core platform.

linkerd

linkerd is an out-of-process network stack for microservices. It functions as a transparent RPC proxy, handling everything needed to make inter-service RPC safe and sane--including load-balancing, service discovery, instrumentation, and routing.

Zuul

It is the front door for all requests from devices and websites to the backend of the Netflix streaming application. As an edge service application, It is built to enable dynamic routing, monitoring, resiliency, and security. Routing is an integral part of a microservice architecture.

Azure Service Fabric

Azure Service Fabric is a distributed systems platform that makes it easy to package, deploy, and manage scalable and reliable microservices. Service Fabric addresses the significant challenges in developing and managing cloud apps.
